Judith 4:15
13 The Lord heard their prayers and had regard for their distress; for the people fasted many days throughout Judea and in Jerusalem before the sanctuary of the Lord Almighty. 14 The high priest Joakim and all the priests who stood before the Lord and ministered to the Lord, with sackcloth around their loins, offered the daily burnt offerings, the votive offerings, and freewill offerings of the people. 15 With ashes on their turbans, they cried out to the Lord with all their might to look with favor on the whole house of Israel.
Galatians 6:10
4 Let each one examine his own work. Then he can take pride in himself and not compare himself with someone else. 5 For each one will carry his own load. 6 Now the one who receives instruction in the word must share all good things with the one who teaches it. 7 Do not be deceived. God will not be made a fool. For a person will reap what he sows, 8 because the person who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit. 9 So we must not grow weary in doing good, for in due time we will reap, if we do not give up. 10 So then, whenever we have an opportunity, let us do good to all people, and especially to those who belong to the family of faith.
Notes and References
"... The phrase 'household of faith' is a significant, and probably a sectarian phrase referring to those who are bound together in a spiritual family by their shared Christian faith and life. 'The phrase is presumably constructed in conscious contrast to the typical Old Testament house of Israel' (e.g., Numbers 20:29; 2 Samuel 1:12; Ezekiel 3:4; Judith 4:15; Psalms of Solomon 17:42), or some such sectarian variant as we find in the DSS - the house of truth in Israel' (1QS 5.6), 'the house of holiness for Israel' (1QS 8.5) ...and 'the house of the Law' (CD 20.10, 13). In which case it will be significant once again that the bonding characteristic of this household is faith, and not membership of ethnic Israel, and not the Torah.' This specific phrase is only found elsewhere at Ephesians 2:19, and in neither case does the context suggest either that there is a particular focus on the fact that the church met in houses at this stage of their existence or a particular focus on some specific group of Christians in a particular location, such as the Jerusalem church ..."
